The Great Gambler (1979) (Hindi Film / Bollywood Movie / Indian Cinema DVD) [DVD]

Vijay is an expert gambler, and has been so as long as he can remember, and
has never lost a game. These skills bring him to the attention of the
underworld, who are interested in hiring him so that he can do as they ask him
to do so. Vijay agrees to do so, and plays successfully, though unknowingly to
entrap a patriotic Indian, to give up military secrets. When the Indian police
come to know of this, they assign the case to Inspector Jai, who is asked to
apprehend Vijay at any cost. The only problem is that Inspector Jai is Vijay's
look-alike, and is not at all a good gambler.
